I get that sometimes, too. A lot of the time I'll hear these loud sounds...like white noise. In the summertime I'll be laying in bed, listening to the crickets chirping and then total silence except for the noise...it will be so loud that it drowns out the crickets. I get those racing thoughts a lot, too. And then thinking about a song over and over and over drives me insane!

I really do wish our brains did have an off button. I think that we'd be much better off!
